Fig. 8 is a side view of the screw-threaded end portion of a rod used with the device and a fusible nut arranged upon said screw-threaded end portion, and.

ployed in all of the said above-described views to indicate corresponding parts.

Referring now to the several figures of the drawings, the reference character 1 indicates a metallic window-frame of any' usual construction, which is provided with a suitablyformed hollow portion 2, forminga chamber, substantially as shown in Figs. 2, 3, and 4 of the drawings. In the lower wall or base 3 of this portion 2 is a suitable hole or opening 4 for the purposes to be presently set forth. The sheet metal from which the frame 1 is made is also provided at the back, at a point below said portion 2, with a suitably-formed and laterallyextending angular shield or rain-drip 5.

One or more window-sashes 6, made of sheet metal, are pivotally suspended or swung in the opening of the window-frame, each sash having an upper hollow portion 7 and a lower hollow portion 8, respectively provided with the channel shaped receiving edges 9 for securing the usual window-glass 10 between said upper portion 8 and lower portion 9. Suitable stops 11 may also be provided at the back on o posite sides of the opening in the windowame 1, against which the window sash is swung, when opened, to limit the pivotal movement of the window, as clearly shown in Fig. 3 of the drawings.

Suitably secured in the upper hollow portion 7 of the window-sash during the process of bending the sheet metal into shape is a lock-casing and its mechanism contained therein, as clearly indicated in the several figures of the drawings. This casing usually consists of two sections 12 and 13, as indicated in Fig. 7 of the drawings, each section being provided with a perforated flange 14, screw-bolts 15 and nuts 16 being employed for securing the sections of the lock-casing against the inner face of one of the sides of the portion 7, substantially as shown in Figs. 3, 4, 5, and 7 of the drawings. One of said sections, as 12, is provided with screw-receiving holes 17, while the other section 13 is formed with interior posts 18, provided with screw-threaded sockets 19, placed directly opposite the screw-holes 17 for the reception of screws 20, by means of which the two sections 12 and 13 are secured together, as shown. A cover or plate 21, provided with a holding-flange or lugs 22, is arranged over the upper open portion of the two connected sections 12 and 13, the said cover or plate 21 being held in place by said flange or lugs 22, and by the inner face of the upper wall of said portion 7. The said cover or plate 21 is provided with an opening 23, and in said upper wall of the portion 7 is a correspondingly-formed opening 24, which registers with the said opening 23, and thereby forms one continuous opening through said upper wall of the portion 7 and said cover or plate 21. Pivotally arranged upon the upper post 10 of the said section 13 is alatch 25, having a recess 26 in its pivoted portion and provided with a lifting end or portion 27. Normally the said latch 25 is in the position indicated in Figs. 4. and 5 of the drawings; but when the window is opened said latch is actuated in the manner to be hereinafter more fully described, whereby its lifting end or portion 27 is moved into the opening formed by the openings 23 and 24, previously mentioned, as clearly indicated in dotted outline in said Fig. 5 and in section in Fig. 7.

Suitably secured upon the inner face of the base of the hollow portion 2 of the frame 1 is a'plate 28, provided with an upwardlyeXtending guiding-socket 29. This socket is preferably of an angular configuration in cross-section, as indicated in the dotted outline in said Fig. 6, which is preferably wider at the top than at the bottom and has a pin 30 extending across its guiding-opening. Movably arranged within the said guidingsocket is a bolt 31, having an elongated opening 32, through which the said pin 30 extends and upon which the said bolt is movably arranged. The lower holding portion of said bolt has a rounded edge 33, and upon its upper end it may be provided with a head or enlargement 34, which normally rests upon the upper marginal edge of the said guiding socket 29 and by gravity forces the lower holding portion of the bolt 31 into and through the previously-nwntioned openings 23 and 24 to retain the window-sash in its closed relation in the window-frame in the manner clearly indicated in Figs. 4 and 5 of the drawings.

Referring now more particularly to Fig. 5 of the drawings, it will be seen that in the front and rear walls of the said upper hollow portion 7 of the window-sash I have placed suitably-disposed and upwardly-inclining openings 35 and 36, respectively, the two sections 12 and 13 being, respectively, provided with semicircular or other suitably-shaped guide portions 37 and 38, in which is movably arranged an upwardlyextending and angularly-inclining tube 39, provided with a teat or projection 40, which extends in operative engagement into the recess 26 of the latch 25. Within the said tube 39 is a rod 41, having an upper shouldered. portion 42,

' connection is destroyed and the sash and'its 1 s5 '6. .The bolt said nut 44 .u-nd

The lowerend the wall and may be portion of the said rod 41 extends from the readily checked from spreading to the other opening 35 in the front pieceof the portion side of the window. The fusible nut or the 7. o the window-sash and is rovided wlth a l plate or link 53 when once destroyed can berom an inspecreceiving eye or 100 545. 1

readily replaced at slight cost and the mechtion of the drawings it will be seen that the anism again restored for further usefulness. er normal conditions rests It will also be-seen that the said shield or upon theupper edge of the tube 39 to prerain-drip 5 protects the'fusible nut 44 against vent the displacement of :thesaid rod 41 from corrosion by preventing the rain and the like .7 5 said tube 3.9. It will also be noticed that from beating upon the nut. the weight of the pivoted latch 25 under In -Fig. 10 1: have illustrated a slightlynormal conditions, indicated-in Fig. 50f the modified arrangement and construction of the locking mechanism. In this constr1'1ction, in which the general construction of the parts is practically the same as the hereinabove described, the tube 39 is movably arranged upon a long support 54, extending he opening 35 to the opening 36 in the I opposite sides of the casing. The latch 25 in this-construction is also of a slightly diflerent configuration, being provided with a long curved edge55, on which the holdingend of V f the bolt 31 rides, as indicated in the dotted y 1 outline in said Fig. 10, and is raised and lowered in a-similar manner to. that previously described.

Having thus described my invention, what claim is, v
